It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

Students explore genetic terms, the Law of Dominance and the contributions of Gregor Mendel. After discussing Mendel's lab and his pea plants students observe examples of a phenotype chart. Afterward, they conduct their own lab to...

Seventh graders examine natural variation by visiting the Ohi'a Common Garden in Volcano, Hawaii. In this natural selection lesson, 7th graders study background information about phenotypes, genotypes, and phenotypic plasticity before...

Students construct Punnett squares to illustrate specific genotypic and phenotypic genetic outcomes. Students calculate the probability of achieving specific genotypic and phenotypic genetic oucomes, using dihybrid Punnett squares.

In this genetic worksheet, high schoolers examine how gene frequency changes in a population of organisms. After completing 5 pre-lab questions, they work in pairs to collect data and answer 5 additional post-lab questions.

Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

Young scholars make a yeast dihybrid cross and follow two forms of each of two traits: red growth versus cream color, and tryptophan-dependent versus tryptophan-independent.

Students explore Punnett squares and illustrate specific genotypic and phenotypic genetic outcomes. After a class discussion, students predict the probability of a specific trait being passed on by using Punnett squares. They reveal the...

Eighth graders become familiar with Punnett squares, specifically purpose, application and interpretation. Key terms from previous lessons (included below) are reviewed/reinforced before data is applied to a Punnett square and interpreted.

Twelfth graders investigate the inheritance of traits through several hands-on activities that illustrate the transmission of genetic characteristics. Students study advanced topics including multiple alleles, polygenic traits,...

Students explore neurological disorders. They examine the presence and absence of discernible genes. Students describe neruological diseases and draw faces of affected persons. They play a human neurology disorders learning game.

Students observe and record observations of whether a person is a taster or nontaster. They test selected individuals from their families and peer groups and chart all findings to determine which trait (e.g. taster or non-taster) is...

Learners review the concepts of incomplete dominance, co-dominance and multiple alleles. As a class, they are introduced to the concept of sex-linked genes and how they are passed to offspring. To end the lesson, they examine possible...

Learners work collaboratively in small learning groups to create some representation of an aspect of Mendelian genetics in this review lesson for the Biology classroom. The lesson includes task cards for each small group and a...

Students describe and apply the Mendellian principles of genetics, focusing predominantly on dominant and recessive genes. They demonstrate how two parents contribute genes and how those genes appear in their offspring. They describe...

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

Students study using analogies between common items or occurrences and science concepts. They use the analogy of cookie recipes to that of the DNA "recipes" for living things to help us explain more about mutations.

Students examine the phenotypic variation within a natural population of a single species. They collect data on the species and analyze the data using statistical/spreadsheet software. Students interpret their results and present their...

Tenth graders work on a project about cellular biology and genetics. In this biology lesson, 10th graders research about the assigned human body system and genetic disorders that affect it. They create a multimedia presentation and...

Learners analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of...

Students examine Punnett squares charts and analyze how they are used for successful breeding and predictions of certain traits. They complete interactive Punnett square charts, quizzes, problems, and concentration games.

Young scholars describe some aspects of known genetic defects on the human neurological condition. They participate in a variety of exercises including drawings, games, and analogies.

Students identify the different kinds of blood. In this biology lesson plan, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.

Students formulate hypothesis based upon data gathered by examining possible crosses of spiderworts using Punnett squares. They present explanations for physiological adaptations of spiderworts that resulted from interactions within the...
